Stuck at Burn Fuses

Postby zitt » Tue Sep 08, 2015 9:39 pm

I'm trying to recover some reset disabled Tiny13A's using the HV Rescue Sheild 2.1 which I just received and assembled tonight.
I'm not having any luck getting past the Burning Fuses... prompt:

Select mode:
1: ATmega (28-pin)
2: ATtiny2313
3: ATtiny (8-pin) / HVSP
Selected mode: ATtiny/HVSP
Insert target AVR and press button.

Existing fuse values:
LFUSE: 4
HFUSE: 4

Enter desired LFUSE hex value (ie. 0x62): 6A
Enter desired HFUSE hex value (ie. 0xDF): FF
Burning fuses...

... it just hangs here forever
Any ideas?

What Arduino hardware are you using and what version of the sketch?
The latest version is here: http://mightyohm.com/files/hvrescue21/H ... sketch.zip

Those look like invalid fuse values, so it seems like the shield is not talking to the AVR.

Make sure the ATtiny13A is plugged in the correct direction! (pin 1 is on the left). Have you tried another ATtiny to make sure the 1st one isn't damaged?

yes; was using 212.
The hardware is a Adafruit Metro which according to their site is a UNO.

I tried a different chip... several actually. similar results.

That is strange. I haven't used the Metro but it seems to be compatible with the Arduino Uno.

Double-check all of the components on the rescue shield and make sure your solder joints look good. Also make sure the sockets are soldered well and no pins are shorting to each other.

If you have access to an Arduino Uno, try using the shield with that board. The Uno is what I use for development and I know it works.
